Future transmission methods in mobile radio and broadband communication call
for wider transmission bandwidths to handle increasing data throughput. Today,
multiple carriers of a GSM or 3GPP base station are often boosted in common
power output stages to reduce the technical effort and cost. This approach on the other hand increases the bandwidth to be transmitted. In both cases, analysis bandwidths exceeding those provided by most spectrum analyzers are required in development and production, while at the same time the dynamic range must satisfy stringent requirements.

The FSG is ideal for applications in the development and production of the
following:

3GPP and GSM-MCPA

WiMAX

LTE

Wireless LAN (WLAN)

It additionally supports measurements on 2G, 2.5G, and 3G mobile radio systems when using application firmware such as:

GSM/EDGE, FS-K5

3GPP FDD, FS-K72/-K73

HSDPA, FS-K74

CDMA2000 FS-K82/-K83/-K84/-K85

TD-SCDMA, FS-K76/-K77

The operating concept of the FSG is identical to that of the FSQ, FSU, and FSP spectrum analyzers, including the GPIB/IEC commands. These instruments thus offer a uniform platform for a variety of applications.

The FSG family

FSG8- [9 kHz to 8 GHz]

FSG13- [9 kHz to 13.6 GHz]

The FSG is a full-fledged high-performance spectrum analyzer:

84 dB ACLR for 3GPP with noise correction

77 dB ACLR for 3GPP multicarrier signals (4 adjacent carriers)

TOI >+20 dBm, typ. +25 dBm

1-dB compression +13 dBm

Displayed average noise level (DANL) - 158 dBm (1 Hz bandwidth)

Phase noise - 150 dBc (1 Hz) at 10 MHz carrier offset

Phase noise - 114 dBc (1 Hz) at 10 kHz carrier offset

In addition to broadband demodulation capabilities, the FSG provides the dynamic range that is required for multicarrier measurements or the measurement of spurious emissions at base transceiver stations (BTS).

With its wide range of functions, the FSG is practically unparalleled on the spectrum analyzer market. Even the base unit comes standard with all important functions.
